Installation Adjusting Projected Image Position Using PureShift Horizontal Lens Shift Lever Vertical Lens Shift Lever The PureShift feature provides a lens shift function that can be used to adjust the position of the projected image either horizontally or vertically within the range detailed below. PureShift is a unique system that provides lens shift while maintaining a much higher ANSI contrast ratio than traditional lens shift system. ▀■ Adjusting the vertical image position The minimum vertical image offset is fixed at 5% of the image height above the centre of the projector lens. This can not be changed. The vertical image height can be adjusted between 5% and 30% of the image height. Note that the maximum vertical image height adjustment can be limited by the horizontal image position. For example it is not possible to achieve the maximum vertical image position height detailed above if the horizontal image position is at maximum.
